Calming Minds Study

3. maj 2026 opdateret af: Michelle Craske, University of California, Los Angeles

Understanding the Mechanisms Driving the Reduction of Repetitive Negative Thought

The goal of this study is to understand why certain treatments help people reduce repetitive negative thinking (RNT), which is common in many mental health problems. We want to:

  1. Figure out what actually causes repetitive negative thinking to decrease when people use cognitive-behavioral therapy (CBT).
  2. Find out which parts of RNT-focused CBT are the most important - the parts that truly make a difference in reducing RNT.

The main result we will look at is how much a person's repetitive negative thought patterns change from the start of the study to the end of treatment (16 weeks). We will measure this using the Perseverative Thinking Questionnaire at baseline and week 16.

Studieoversigt

Detaljeret beskrivelse

Participants in this study will be randomly assigned to one of 16 different treatment groups. Each group will get a different mix of 1-5 tools or strategies taken from Rumination-Focused Cognitive Behavioral Therapy (RF-CBT).

All participants, regardless of their treatment assignment, will get a basic set of lessons about repetitive negative thinking (RNT) and how CBT can help. This means every participant gets therapeutic support.

Participants will use a digital therapy program through the MyDataHelps app. The CBT lessons are available in English or Spanish, according to the participant's preference. Each participant will also be offered 3-6 meetings with a coach from our team, to review the lessons and tools in the digital therapy program. It is expected that the digital therapy program and coaching sessions will be completed within 4 months on study. Once 4 months have passed since their start on study, participants are asked to complete online questionnaires that will measure their recent symptom experiences. Participants are then asked to complete these questionnaires again 1 year after starting on study. These questionnaires are used to measure changes in symptom experiences from baseline (before starting the digital therapy program).

In addition to the primary goals listed in the brief summary, this study also aims to look at the following:

  1. How anxiety and depression symptoms change during their use of the digital therapy program.
  2. Whether people's mental health symptoms change over time after using the digital therapy program.

d) Who benefits most from which components, so therapy can be more personalized in the future.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Aktiv komparator: Psychoeducation Only
Participants receive only core psychoeducation without any additional RF-CBT components.
Digital therapy lessons and coaching that provide foundational information about repetitive negative thinking and why it occurs. Helping participants understand explanations for their symptoms and difficulties, which reduces the search for understanding, insight and certainty shown to drive RNT, and normalizes their experiences. This corresponds with the RF-CBT components of individualized rationale, psychoeducation, empathy and understanding.
Eksperimentel: Be Specific
Participants receive training in increasing specificity and concreteness ("Be Specific") in addition to standard psychoeducation.

This corresponds with the RF-CBT components of individualized rationale, psychoeducation, empathy and understanding.
Digital therapy lessons and coaching that emphasize skills in shifting from unhelpful abstract to helpful concrete processing style. Helping participants make changes to processing style to improve problem-solving and reduce emotional reactivity. Training concrete thinking to reduce RNT by increasing specific contextualized detail in description of events and plans.
Eksperimentel: Be Kind
Participants receive training in self-compassion ("Be Kind") in addition to standard psychoeducation.

Eksperimentel: Break Habit
Participants receive training in breaking the habit of repetitive negative thinking ("Break Habit") in addition to standard psychoeducation.

Change in repetitive negative thought (RNT) in everyday life measured with ecological momentary assessment (EMA) (aggregrate person-level ratings of RNT across 10 day period; variability of RNT; relationship of RNT to mood state & contextual events; automaticity of RNT, based on EMA items). This provides an ecologically valid measure, in the real-world, of extent of RNT and how it changes pre-to-post intervention.
